New and very simple synthesis formulas for coplanar strip line

Neural Models for Coplanar Strip Line Synthesis

“…A similar perfect agreement between the results of the neural models and quasi-static analysis is also achieved for all CPS structures to be designed with different electrical parameters and physical dimensions. It was found that the average percentage error values of the neural models, the synthesis formulas proposed by Deng et al [10], by Yildiz [11], and by Yildiz et al [12] are 0.24%, 0.84%, 1.43%, and 1.25% for all possible 10614 CPS structures, respectively. These results certainly show that the proposed neural models for CPS synthesis are more accurate than the synthesis formulas available in the literature.…”

“…(5) can also be determined from the following eqs. (7) and (8) proposed in [11] and [12], respectively.…”

“…The model proposed by Deng et al [10] is mathematically complex. The models presented by Yildiz [11] and Yildiz et al [12] are simple but do not have very good accuracy. Hence, they are not very attractive for the CPS synthesis.…”

“…These neural models were trained with LM [25], BR [26], QN [27], CGF [28], and SCG [29] learning algorithms to obtain better performance and faster convergence with a simpler structure. For the validation of the neural models proposed in this paper, the neural synthesis results have been compared with the results of the quasi-static analysis [6] and the synthesis formulas proposed by other researchers [10][11][12].…”

“…The synthesis models were also presented in the literature [10][11][12]. These synthesis models are directly used to obtain the physical dimensions of CPS structures for the required design specifications.…”
